A New Evolutionary Mechanism Based on Inefficient Selection

The origin of complexity is a key problem in evolutionary theory. How did the blind process construct so many precise and elaborate biological designs? The evolutionary expectation has always been that Darwin’s process of natural selection is the driving force that creates everything from biosonar to the brain. But new research indicates that much of the complexity found in the higher organisms is due not to natural selection, but rather to limitations on natural selection. It is yet another new evolutionary mechanism in a dizzying list of new, and ever more complex, mechanisms. Read more
